SPECIFICATION forming part of Letters Patent No. 342,622, dated. May 25, 1886.

Application filed February 1], IBFG. Serial No. 191,637. (No model.)

To aZZ whom it may concern.-

Beit known that I, JAMES MolLwAIN, a citizen of theUnited States, residing at Okaw ville, in the county of WVashiugton and State of Illinois, have invented certain new and useful Improvements in Ohurns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make IO and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked theron, which form a part of this specification.

Figure 1 of the drawings is a side view of my mixer and beater. Fig. 2 is a vertical section of the same. Fig. 3 isa view of the beaterframe. Fig. 4 is a detail view.

My invention has relation to heaters and mixers for mixing and agitating fluids; and it consists in the construction and novel combination of parts, as hereinafter described, and pointed out in the claims.

Referring by letter to the accompanying drawings, A designates the receptacle for re ceiving the fluid to be beaten or mixed. This receptacle A is a vessel constructed of any suitable material, and is of the same diameter throughout its entire height; or it may taper inwardly from the bottom to its top, so that its lowest diameter will be greater than its upper diameter. The vessel A is preferably a permanent part of the mixer; but it is not essentially necessary that it should be such, as

the mixer may be constructed to fit vessels of different sizes, and may be removed from the vessel and stored away when not in use, or may be used in another vessel or vessels after having been used in the first one. It is, however, essentially necessary that each vessel 0 should be provided with laterally-projecting studs B on its outer face near its mouth, in order to secure the sectional cover, one part of which supports the beating and mixing mechanism in place.

0 designates the half or portion of the cover to which the heaters and their holding and operating mechanism is secured. This half or portion 0 is provided with bayonet lugs or catches D, which engage the studs 13 when the 5c portion or section 0 of the lid or cover is in place on the vessel A. These studs B and catches D hold the lid firmly in place while the gearing is being operated in one direction; but in order to prevent movement of the halflid when the gearing is being operated in theopposite direction a stop or stud, E,is provided on the outer face of the vessel A at any desired place, and a hinged catch, F, is secured to the section 0 of the cover, which catch, when turned down and brought into en- 50 gagement with the stud or stop E, prevents the cover from slipping or turning on the mouth of the vessel A when the mixing mechanism is being operated thereon.

To the under face of the section 0 of the cover is secured a frame, G, which forms a stationary beater when in place in the vessel A. Near the upper ends of the vertical arms ofthis stationary beater or frame G are pivoted the upper ends of the vertical arms H of the adjustable beater H, the lower ends of said arms H being connected by links or arms I, hinged to each other attheirinner or meeting ends by alink, I, or otherwise, and hinged to thelower ends ofsaid arms H by links 1 The link-arms I permit the adj nstment of the arms of the beater H, to effect the entrance of the agitators into the vessel A,and to permit their removal therefrom when necessary. Furthermore, the arms H, when thus connected, may be moved or projected apart after having been e11- tered into the vessel A, to cause their outer edges to fit closely to the inner side of the vessel A,so that thefluid subj ected to agitation cannot pass between the arms H and the side of the Vessel, but will strike said arms H and be deflected thereby inwardly upon or against other portions of the fluid under agitation.

J designates a bracket secured to the upper face of the section 0 of'the cover. Said bracket 0 J is strengthened by a brace, K, and forms the hearings in which the beater-shaft L revolves.

To the lower end of the beater-shaft L is rigidly secured an inner open beater or frame, M, which has its lower bearing on a stud or 5 short shaft, M, rising from the cross-arm M of the frame G. The shaft L revolves within a vertical sleeve, N, having a pinion, N, at its upper end, which pinion N engages the drive-wheel 0, having teeth on one face there- :00 of, said engagement being effected at the lower side of the Wheel .0. About midway of its length the sleeve N is provided with a dripcnp, P, which prevents oil from passing from the gearing down into the vessel A. At its upper end the heater-shaft Lis provided with a pinion, Q, which engages the drive-wheel O and rotates the beater-shaft and inner heater in a direction opposite to that in which the outer heater-frame is rotated. The drivewheel is provided with a handle by which to turn it, and by this handle the drive-wheel may he turned in either direction to impart motion to the heaters. The lower ends of the beater-frames are journaled on a short central stud or pivot, M, and upon the upper end of this stud a disk, T, is secured, and forms a friction-plate near the bottom of thcvessel, whereby the currents may befirst concentrated, and then thrown upward and outward.

This entire device may he used as a heater and mixer of fluids, batters, and the like, or it may be used as a churn, and will act with rapidity and positiveness in either capacity.

Having described this invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the section 0 of the cover, provided with the bracket J, of the beater-shalt provided with a pinion at its upper end and the inner rotary beater at its lower end, the sleeve incasing the heater-shaft and provided with a pinion at its upper end and the outer rotary heater at its lower end, the

stationary beater G,and the adjustable beater H, connected by thelink-arms I, and the drivewheel for moving the rotary heaters in opposite directions, substantially as specified.

2. The combination, with the vessel A, having outwardly-projecting studs near its mouth, of the sectional cover provided with the bayonet-fastenings and the hinged catch F, substantially as specified.

dasher and rotary dashers, of the. adjustable frame or heater H, having the hinged connecting-links at its lower end, substantially as specified.

5. The combination, with the stationary dasher, of the adj ustahle vertical arms pivoted thereto and connected at their lower ends by the links, substantially as. specified. I

In testimony whereof Laflix my signature in presence of two witnesses.

JAMES NIGILVAIN.
